This Monday I’ll be talking at the Amsterdam R meetup, better known as amst-R-dam. At their request I’ll discuss the differences between the New York and Silicon Valley data scenes. Time permitting I’ll also go over some topic that I’ll let the audience choose.
Thanks to Rachel Schutt, who I’m teaching with at Columbia, and Cathy O’Neil from MathBabe I had the opportunity to go on TV and talk about the statistics of tonight’s Powerball lottery.
There’s an article with a brief quote from me and a video where I may a very quick appearance at the 1:14 mark. My interview during the live broadcast actually went on for about three minutes but I can’t find that online. If I can transfer the video from my DVR, I’ll post that too.
In the longer interview I discussed the probability of winning and the expected value of a given ticket and other such statistical nuggets. In particular I broke down how choosing numbers based on birthdays eliminates any number higher than 31 mean you are missing out on 28 of the 59 possible numbers that are uniformly distributed. Hopefully I’ll find that longer cut.
A friend of mine has told me on numerous occasions that since 1960 the Yankees have not won a World Series while a Republican was President. Upon hearing this my Republican friends (both Yankee and Red Sox fans) turn incredulous and say that this is ridiculous. So I decided to investigate. To be clear this is in no way shows causality, but just checks the numbers.
The plot above shows every Yankee win (and loss) since 1960 and the party of the President at the time. It is clear to see that all nine Yankees World Series wins came while a Democrat inhabited the White House. The fluctuation plot below shows Yankee wins both before and after 1960 and the complete lack of a block for Republican/Post-1960 simply makes the case.
There are similar plots for the American League after the jump.
